Grillo Leads TPC Twin Cities After Round 1, But Scheffler Looms

Emiliano Grillo has seized the early advantage at the 3M Open in Blaine, Minnesota, posting a Round 1 score good enough to put him atop the leaderboard — a performance the money decisively backed only after he was already deep into his round. The deeper story, however, is that one first-round lead has done nothing to shake the tournament's central conviction: Scottie Scheffler remains the man to beat.

The cluster of markets around this event reads as a coherent two-act narrative. Act one belongs to Grillo, whose name shot to the top of the Round 1 leader market on enormous volume as his score materialized. Act two, the one that actually concerns bettors with money on the full tournament outcome, still resolves around Scheffler. His outright winning probability climbed sharply over the past day and now sits near 40% — a commanding plurality in a field of more than 150 professionals where no other name cracks double digits. Michael Brennan, Jackson Koivun, and Lucas Glover cluster in the low single digits, the kind of diffuse spread that signals a field offering no credible challenger consensus.

One cross-venue quirk deserves a candid look: the outright winner market prices Scheffler in the high thirties to low forties across the two major venues, but a sharp discrepancy exists between them on at least one other competitor — a gap of roughly 40 percentage points on the same question. The deeper market by an enormous margin, carrying more than a thousand times today's trading volume on the other side, stands firmly with the lower number. That asymmetry suggests the thinner venue may be carrying stale or unsophisticated liquidity rather than a genuine informed disagreement. The Scheffler consensus, backed by the heaviest volume, is where the real conviction lives.

What brought money here so decisively is no mystery in outline, even if the precise timing is. Scheffler has spent the better part of two years making weekly bets against him feel foolish — major titles, FedEx Cup points, world ranking dominance. TPC Twin Cities is a birdie-fest that rewards ball-striking, and Scheffler's ball-striking is, by most measurable accounts, the finest on tour. A field without another elite presence capable of consistently matching him stroke for stroke makes the implied 40% feel less like an overreaction and more like a floor.

Grillo's position matters, though not because the money believes he wins. At 5% to take the tournament, he is a live threat for weekend drama, not a consensus successor. The interesting read is whether his lead compresses or evaporates as Scheffler — whose first-round score the market has not yet fully digested — makes his way up the board. If Scheffler enters the weekend within striking distance, the outright odds will likely tighten further around him. The scenario that breaks the market's thesis is a Scheffler stumble across rounds two and three, which would suddenly make the diffuse single-digit field a genuine open race. Until then, this tournament is his to lose.

For the casual observer, the 3M Open's story this week is a familiar one: watch the spectacle of a field chasing a man who has made the hunt look routine. For those reading the money, the more interesting signal is structural — a 40% favorite in an outright field this large implies a level of dominance that the sport rarely prices in for any individual. The depth and decisiveness of that signal, on this volume, is not noise. It is the crowd's considered verdict on where the Claret Jug's next chapter is most likely written — even if Grillo, for one afternoon in Minnesota, has the first word.
